Each winter deciduous trees lose their leaves, stop growing, and go
into dormancy--a built-in genetic defense against cold weather damage.
But sometimes cold weather occurs when the trees are not in dormancy,
and then trees can suffer severe damage. Now researchers have discovered
a single gene that appears to control dormancy in peach trees. Called
"EVG," this gene could lead to developing peach trees that are less
vulnerable to fall or spring freezes. Scientists found the dormancy-
control gene in evergreen peach trees in Mexico. The research represents
a joint effort of ARS (USDA-Agricultural Research Service) in Byron, GA,
the University of Florida, and the Colegio de PostGraduados in Chapingo,
